Meet Our Teachers & Staff
Pacific Crest is accredited through the AdvancedED. All of Pacific Crest’s Primary and Elementary teachers are trained through Association Montessori Internationale (AMI) training centers. Our Middle School teachers attend Montessori trainings for the adolescent level; these are offered by the North American Montessori Teachers Association (NAMTA) in partnership with AMI.
